Hello and welcome to OpenStudy. First, can you write out the balanced chemical equation for this reaction?

anonymous · Answer

I am not sure how to get the equation out of the word problem

wolfe8 · Answer

Well you know you burn propanol with the presence of oxygen. So you  have on the reactant side: C3H8O + O2

And combustion of carbon compounds will give you on the product side: CO2 + H2O
The second part is usually something you just remember. 

Now, can you write that into an equation and balance it?

anonymous · Answer

I balanced the equation and I got C3H8O+3O2 --> 3CO2+4H2O

wolfe8 · Answer

I don't think your O is balanced there

I have 7 oxygens on both sides? |dw:1389650267546:dw|
